IMPROVED DRILLING-MACHINE.-

Specification forming part of Letters-Patent No. 5 I I 89, dated November 28, 1865.

To all whom it may concern:

Be it known that we, ANDREW P. JACKSON and LEANDER THOMPSON, of Memphis, in the county of Clark and State of Indiana, have invented a new and Improved Drilling-Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawing, forming part of this specification, in Which- Figurel is aside View of our machine, partly in section; Fig. 2, a front View of the same; Fig. 3, a plan or top view of the same.

Similarletters of referenceindicatelikeparts. This invention relates to a new and improved drilling-machine designedfor general use, but more especially for boring deep wells.

Theinvention consists in a new and improved means employed for operating the drill and for raising the same out of the well when required.

A represents a framing, which may be constructed in any proper manner to support the working parts, and B is a cam fitted in said framing, and provided with two prominent surfaces, a a, as shown clearly'in Fig. 1.

O is a lever fitted in the framing A, against oneend of which the cam B works.

D is-a Windlass, which is placed in the framing A in line with the shaft 1) of the cam B.

The shaft I) of this Windlass is allowed to slide in its bearings, and one end of it is connected to the end of the shaft 1) of the cam B by means of a clutch, E, which is connected and dis- I is a'rope, which passes around the windlass I) and over a pulley, J, at one end of the,

framing, saitl rope having a drill, K, attached to its lower end and L is a rope, which is attached to the outer end of the lever 0, passes over a pulley, M, and is connected to the drillrope I, as shown clearly in Fig. 1.

From the above description it will be seen that as the cam B is rotated the lever U will be operated and an up-andd0wu motion given the drill K, the rope I of the Windlass being letout from timeto time and the ropeL slipped or adjusted on rope I from time to time, as the rapidity ot' the work of the drill may require. The drill is drawn out from the bore by connecting the Windlass D with the shaft of the cum B and rotating the cam, and the drill may be let down to its work with the requisite speed by means of the brake H, which contros the motion of the Windlass.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The cam B and lever U, in combination .of the cam-shaft.

The above specification of our invention, signed by us this 22d day of June, 1865.
